CityNightLine through coaches stored in Dresden Hbf. These three
cars (double deck sleeping-car WLABm, couchette car Bvcmz and
sleeperette car Bpm) are operated as CNL "Semper" between Dresden
and Zürich every night. As you can see from the cable and warning 
sign, the train is connected to stationary 1000 V electricity.
